Insulation installer insurance after a claim is cover for cavity wall, external wall and other insulation businesses that have had liability claims, complaints or remedial work, often relating to damp or defects in past installations. Many mainstream insurers decline or exclude installers with a claims history, particularly for cavity wall work, but specialist markets will still offer cover when the risk is presented properly. Insurers want to understand what went wrong, how many claims there were, whether they relate to old schemes or current work, what has changed in your surveying and installation process, and how you handle complaints now. Higher excesses or specific exclusions may apply at first, but terms usually improve with a clean record.

Had claims against your insulation business? We'll present your history properly and find markets that will still offer cover.

Key facts at a glance

  1. A claims history doesn't end your options. Specialist markets look at what has changed, not just what happened.
  2. Old scheme claims are viewed differently. Claims from historic installations can be separated from current work.
  3. Process changes carry weight. New surveying and sign-off processes reassure underwriters.
  4. Expect stricter terms at first. Higher excesses or exclusions are common for the first year or two.
  5. Disclosure is essential. Every claim and complaint must be disclosed.

Can you get insurance after insulation claims?

Yes, in most cases. The key is a clear, honest presentation that explains the claims and shows how your business has changed.

Insulation claims often relate to work done years ago, sometimes under schemes with different standards. Insurers will want to separate legacy claims from current work and understand whether today's installations carry the same risk. A business that now surveys every property, refuses unsuitable walls and keeps full records is a very different risk from the one that did the original work.

This is the kind of risk we place every week, building on our experience with business insurance with a claims history.

What information do insurers need?

A good claims presentation answers the underwriter's questions before they ask them.

What terms should you expect?

Expect insurers to protect themselves in the first year, then improve terms as your record builds.

  • Higher excesses on products liability claims
  • Exclusions for specific measures or historic work
  • Conditions on surveying and record-keeping
  • Lower limits than you might want at first
  • A retroactive date that excludes earlier installations
Understand the retroactive date

Some policies only cover work carried out after a set date. That may leave historic installations uninsured, so check what cover, if any, remains for older work.

How can you rebuild your insurance record?

  1. Disclose everything. Non-disclosure can void the new policy.
  2. Show what changed. Processes, training, products and management.
  3. Keep claims-free. A clean year makes a big difference.
  4. Handle complaints early. Resolve issues before they become claims.
  5. Review terms each year. Push for improvements as your record improves.

About this article General information, not advice. Published for general guidance and drawing on external sources as well as our own experience. It is not a personal recommendation, a quotation, or an offer of cover, and it doesn't take account of your circumstances. Read more + Close −

Where the information comes from

Our articles are compiled from a range of sources: regulators and public bodies such as the FCA, the Civil Aviation Authority, the Health and Safety Executive and Companies House; government publications and legislation; industry and trade bodies; insurer and market documentation; and published research and news reporting. Not everything stated originates from Miller & Partner. Where information comes from a third party we believe it to be accurate at the date of publication, but we haven't independently verified every external source and we don't warrant its accuracy or completeness. Where a point matters to a decision you're making, go to the original source and check it.

Figures, examples and case studies

Premium ranges, cost figures, limits and worked examples are illustrative only. They are not quotations, not offers of cover, and no cover is provided or implied on the basis of them. What you're actually charged depends on underwriting, and what you're actually covered for depends on the policy wording issued to you. Where an article includes a claim example, scenario or case study, it is illustrative unless we say otherwise — such examples are typically composites written to show how a policy section responds, and they don't describe an identifiable client, claim or settlement.

Interactive tools

Any calculators, cover checkers, risk assessors or similar tools on our site produce general guidance from the small number of answers you give them. They can't see your business, and their output is not a personal recommendation, an assessment of your actual risk, or a quotation.

Rules and market conditions change

Law, regulation, tax treatment, insurer appetite and policy wordings all change, sometimes at short notice. Content is accurate to the best of our knowledge on the date shown on the article and we don't undertake to update it as things move. An article you're reading some time after publication may be out of date.

Third parties and external links

References to insurers, underwriters, trade bodies, software, training providers or other organisations are for information only. They don't imply endorsement, recommendation, partnership or affiliation in either direction unless stated. We're not responsible for the content of external websites we link to.

Not legal, tax or accounting advice

Nothing here is legal, tax, accounting or regulatory advice. Where an article discusses statutory duties, contract terms or compliance obligations, take advice from an appropriately qualified professional on your own position before acting.
